The functional role of spinal and supraspinal EMG-responses for the maintenance of upright human posture was investigated in ten healthy subjects standing on a force measuring platform, which could be rotated in pitch around an axis aligned with the subject's ankle joint. Voluntary changes of body posture prior to the platform movement by leaning forward or(More)
The functional role of short-, medium- and long-latency responses for the maintenance of upright posture was investigated in twenty healthy subjects standing on a platform which could be rotated in pitch around the subject's ankle joints. Tilting the platform toe-up evokes a stretch reflex in the triceps surae muscle (TS, latency 55–65 ms) and at higher(More)
The aim of this study was to proof applicability of hyperspectral imaging for the analysis and classification of human mucosal surfaces in vivo. The larynx as a prototypical anatomically well-defined surgical test area was analyzed by microlaryngoscopy with a polychromatic lightsource and a synchronous triggered monochromatic CCD-camera.

RATIONALE The incidence of translaryngeal tracheotomy (TLT)-associated peri- and postoperative complications should be assessed prospectively. METHODS TLT was carried out in operation-theatre under rigid endoscopic control. Peri- and postoperative complications, decanulement and late sequelae were assessed in ENT-patients. In patients of other wards only(More)
Epidemiological studies in endemic geographic regions for esophageal squamous cell carcinoma (ESCC) suggested a number of risk factors, including modifications of the p53 tumor suppressor by codon Arg72Pro polymorphism, loss of heterozygosity (LOH) or human papillomavirus type 16 or 18 (HPV 16/18) infection. The p53 Arg72 variant has been suggested to be a(More)
After craniofacial resection for ethmoid and nasal cancer the resulting defect in the anterior base of skull often is a problem because of liquorrhoea, followed by meningitis and brain herniation. Two approaches were used for surgery of ethmoid and nasal cancer involving the anterior base of skull — the transfrontal and the transethmoidal. The neurosurgeon(More)
Otoacoustic emissions (OAE) are influenced in their amplitude and frequency spectra by the middle ear. The effects of changes in the middle ear transmission mechanisms on transiently evoked OAE (TEOAE) and distortion product emissions (DPOAE) were investigated as a function of static ear canal pressure in 25 normal-hearing test persons aged 18–35 years. The(More)
During recent years, a significantly increased incidence of acute mastoiditis was observed at the University Children's Hospital, Tübingen, Germany (1975-1979: 1.4 patients/year; 1987-1992: 4.2 patients/year; p < 0.05). We therefore reviewed the records of all patients with acute mastoiditis (n = 58) that had been treated at the Children's Hospital between(More)
Tobacco and alcohol have been identified as the most important risk factors for squamous cell carcinomas of the head and neck (HNSCC). Especially for tobacco, some of the carcinogen-induced mutations that trigger transformation have been identified. Much attempt has been made to show a relationship between the mutations of growth regulatory genes, i.e.(More)
Epistaxis is a common clinical problem, and the majority of bleedings can be managed conservatively. However, due to extensive and sometimes life-threatening bleeding, further treatment, such as superselective embolization, may be required. We report our experience with endovascular treatment of life-threatening epistaxis. All patients presenting with(More)
